- The resolution keyword is deprecated in favor of quad_segs to align with Shapely's convention. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)

### New APIs and options

- Adds a grid_size parameter. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)
- Generates square or hexagonal grids covering the input geometry. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)

- Generates square or hexagonal grids covering the input geometry. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)
- Adds a grid_size parameter. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)

- When plotting continuous variables with a classification scheme, setting colorbar=True within legend_kwds produces a colorbar instead of a categorical legend. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)
- The value "greedy" enables greedy topological coloring so adjacent polygons do not share a color; it requires mapclassify and libpysal. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)
- Static plots can include a basemap through contextily.add_basemap; the contextily package is required. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)
- With the pyogrio engine, fid_as_index=True accesses the feature ID as the index. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)
- Adds a grid_size parameter. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)
- Adds a grid_size parameter. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)

### Fixes and other changes

- Passing multiple non-geometry columns now falls back to pandas multi-column explode instead of raising a cryptic error. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)

- Index levels produced by explode and get_coordinates with index_parts=True are int64 rather than int32 on 32-bit platforms. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)
- read_parquet no longer ignores partitioning when auto-detecting columns, so partitioning=None no longer raises. (1.2.0) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.2.0)

- Correctly handles missing values with pandas 3 when the new str dtype is used. (1.1.3) — [release notes](https://github.com/geopandas/geopandas/releases/tag/v1.1.3)
